"We were not seriously talking about another Army of Darkness until about six months ago," Campbell said. "Now we're actually talking about it and Sam is going to have a whack at it with his brother (Ted Raimi) this summer. That's what he's threatening to do. But this has been threatened before."

Pushed for details on Raimi's plot ideas for the long-planned follow-up, Campbell responded: "There is no storyline. There's zero storyline. There's nothing, no ideas, there are random thoughts on a couple of snaps of paper, napkins and menus. Beyond that, this is a story that has to be pulled out of Sam's brain."

The possibility of bringing together Raimi and Alvarez's film worlds has recently been touted, but Campbell played down talk of an eventual crossover film.

"I think Sam's going to be pretty proprietary about who goes into what universe," he explained. "Nobody ever knows, even us discussing it causes problems because then people will go, 'Oh, they talked about merging it'."

The Evil Dead remake opens in the UK on April 17. Evil Dead II's Special Edition Blu-ray is released today.
